Cheer up Dala! It is going to be a great content, looking forward to see videos about "healing" and bringing this battery to life.

many times I've had repaired cells in new ze1 leafs with leakage from the corners, the cells have really bad hermetization and in 99.9% cases they are quickly repaired by proper sealant. So I insist on disassembling the pack and see what is going on with P0AA6. Anyway everything is going on for the greater good!))

So sorry that your new battery is faulty, especially after all your hard work getting it ready.

I feel your pain, chum. Hope your luck turns soon!

Love the fact the 30kWh battery has the "don't put in a wheelie bin" symbol. Good advice, I got loads of grief from the dust men last time I tried that ;)

Finland is cold as shit. Ha ha ha.

My friend bought a 62kw battery there was water inside fortunately it was not a lot so the cells were not damaged.

Don't give up. The battery can be fixed. Rustproofing battery and car is a great idea. I had my 2012.09 Leaf fully coated with Mercasol when it was new. After over 60000km in just over 1,5 years the underside still looked new. (South-West coast of Norway..) Now there is a lot of Gen 1 Leafs that are being crushed here as they have been used up. Batteries with 3-5 bars, no brakes, fully worn out suspensions, etc.. Soon the Gen1 Leafs will be no more.

Gutted for you Dala! Hang in there, i love seeing new videos from you and hope one day i can do half the stuff you have shown in your videos to my leaf. Good luck finding some replacement cells!

Hi Dala, no luck this time but keep in mind you are doing a so great job that help all of us. Maybe, could swap good cells from the 40 to the bad 62. Why not? Hope you will find a solution, I'm sure you will because we are wainting for the CCS study.......I joke, just putting some pressure. Thanks for everything you share with us. Keep your good attitude, make the world a little bit better.

Appreciate you sharing your experience with us

Sorry to hear that it hurts to lose all that money and labor but I love you work and know you will get through

I’m sorry for you. 😔 But happy I can follow you even longer down the battery-rabbit hole😊😊

Amazing work Dala! I am learning a lot of new things with you. Thank you for sharing your knowledge.

9:02 from leafspy it shows 4 cells, if the layout in bms is kept the same then cells 1-48 is rear stacks. in 64kwh pack there are 4 towered stacks in rear. The faulty ones are in the first stack then.. the good news is that unlike the 24kwh pack - faulty ones cant push on everything when expanding. Only their tower. So if you can source one good rear towerstackj, it can be replaced :) Did the pack have any dents in it? Or maybe marks undenting.. as it's the first pack - it might be some collision damage that some corner hit the tower of cells.

I'm sorry to hear about your pain, Dala! This is real life, and sometimes we don't get to use shortcuts. This 62kWh battery upgrade is one that many people will seriously consider, which is realistically a dependency before it's worth it going ahead with any CSS-related mods. On the bright side, it makes for excellent video material! :-)

As always, great video. Crossing my fingers that you are able to find a solution and salvage the battery pack.

Sorry to hear this Dala, I'm sure you'll find a solution 💚

UGH! we'll i cant wait for your video about a leaf battery as grid storage 😎

Hope you get good luck next time. A lesson to learn for all of us when buying refurbished batteries. Your videos are a great help for us. Maybe this is why repackaging is sometimes better than to get these refurbished OEM ones. With repackaging you can get newer cell chemistries like NCM811 and you know the condition those cells are in. Plenty of space for even more than 62kWh as new cells like NCM811 has higher energy densities than OEM Nissan ones. Then it all comes down to how you mount the cells/modules securely and distribute weight like in OEM modules. There's space for liquid cooling/heating even if you use 355 modules.

I'm sorry looking forward to the update on the new cells

So sorry mate. I feel your pain. Big Q is how those lemons can turn into lemonade. Your content is amazing and the only channel that I have the notification bell on, keep it up!

This is just a bump in the road. Keep up the good work!

We live in New Hampshire. Rust is a major issue here, too. FWIW your videos are helping me to navigate the tricky purchase of a used Leaf with a plan to improve the battery. I have great confidence you will bounce back from this challenging set back.

Really nice rustproofing Dala. Sorry to hear about the cells. If the module can't be fixed, keep an eye out, one will turn up, or find another whole bad 62 pack. Then you're the guy in Europe with spare 62 modules! In my stationary storage, I have 2x 7s modules from a 62kWh pack (not sure if shipping is worth it or possible, but I would send if you need, I guess they're in good condition). But it looks like you need a 9s module.

A mere battery will not defeat Dala the Great! Hope you find the problem quickly and easy to fix.. we always learn something from your pain.. thanks for sharing!

Sorry to hear dude. Early in my leaf tinkering journey but will keep an eye out for some cells in Ireland

It's always the way when you're attempting to do the impossible, that you will have setbacks. Take encouragement from the fact that you have managed to fit the battery into the car in the first place. I'm sure you will find cells to replace the broken ones or another battery. As we say in England.....'chin up'.

So sorry to hear this Dala. Rotten Luck.

Muchos ánimos Dala !! Seguro que con tus conocimientos la podrás reparar.

Thanks for sharing this experience also. After some fails the success feels even more sweet!😉

Yo, good stuff man. Hope you get to the bottom of it. Love your workshop, wish I could help. But anyways keep on it, you’ll get there soon!!

"i'm in Finland, and its cold as shit here" love it.

I think you'll figure it out. You are smart! God bless!

Sorry for your pain Dala. Sometimes bad things happen to good people.Sorry again. 40 goes back in while you source parts to repair your 62. Once you confirm what has failed ,and what you need to get it going again, I am sure people will come forward with the parts you need. Perseverance prevails.

Sorry to see you're having trouble 😢

Battery will have to be used as house storage,gutting problem to find hope you get sorted,Dala thanks for showing.

‘Speaking of over-doing it’…great approach.

Thanks Dala to try all this < good Luck to you . The community loves your work Cheers Michael

Hope you manage to turn this project around

What a pain! I would love to see a tear down and bad cell identification video of the battery pack. Fingers crossed you can get hold of replacement cells.

Ei aina mee niinkuin Srömsöössä. Kiitos hyvistä videoista! Uusia odotellen ja toivottavasti löytyy akkuun tervettä palikkaa! It's not always like in Srömsööö. Thanks for the good videos! Looking forward to new ones and hopefully find a healthy chunk in your battery!

If there is someone who has the skills and attitude to overcome this problem is you. Maybe you have luck when opening the battery pack you find the leakage not inside the cell but any interconnection module strap or BMS connector... Cheers

Keep going Dala!

My sympathies.

My 30kWh having same issue. I’m also fed up with that

Mit Kuhlu from Australia. You are a Fin and Fins never fail. You had a sh|t day but you will bounce back. Good luck and if you ever visit Perth I'll buy you Finlandia and dinner.

Looking forward for the video you have on the high voltage battery pack to charge controller to inverter!

I am so sorry to hear about the bad battery, when you put all that effort into it, I think there are a couple of companies starting to make the legacy Leaf battery from a NZ youtube channel I was watching

You'll figure it out man!

Great videos. So much work, I hope you'll find some spare modules soon. You seem to know the Leaf through out - I'm installing parking sensors in my one is there any way you can think of telling the system car is in "D"? In my tekna "D" allows you to use frontcam and goes off when accelerating I wonder if this could be used?

Good work. At least you can make undo, with an upgrade.

Thank you for the information my man :) im considering this upgrade in a couple years if my leaf prooves to be reliable for me. :)

if you do split the pack and find the broken cells, you may be able to get replacements internationally, as that may be a quicker way of getting your 62kwh pack running. otherwise you could sell your cells to recoup some (all?) your costs. Best of luck Dala

Sometimes it helps just to open the pack and remove the cells, get them rebalanced and reinstall. Properly torque all connectors. A lot of work, but no expensive replacement parts needed.

Don't give up. This is such bad luck :(

You are the master on this take the battery about find the bad and try to reset that cell

I just choked on my morning coffee, took a swig right as you said "I'm in Finland and it's cold as shit here" 😂😂😂😂😂 Just thinking if you lived in a hotter climate painting it with silver or white paint to help disopate heat might be a good idea

Well the good news is if anyones gonna find a way around this... that is you !

I feel for you. That's quite a lot of money to invest to have it fail. I have also read insurance is very high on electric cars.

Find the leaky module inside and build a thin catch tray so it doesn't ground out. Worth a try maybe.

Ouch! It would have been nice to check the battery before painting 🖌️ 😮

Dala. you a real hero for us. You saved several thousands of money in the future via us :)

Too bad! You can use it to make some powerwalls and sell them to some solar nerds, maybe 4-5 pcs and some additional material snd maybe some bms if needed, that would be awesome project to watch

great video uplaod more :)

Super Video. Did you Check for torsion?

that's a bummer!

9:02 leaf spy says 1800+ DC charging :o maybe the heat ruined those cells

Buy Fluke 1507 to check isolation before installing the battery. I think installing 40kWh back and investigating the issue is way to go. I feel your pain, because I just repaired my Focus Electric isolation issue. Maybe you have to open bursted modules and renew those dead cells. But do not worry, we EV enthusiasts need these kind of experiences to learn about working with these. It feels bad now, but will give you knowledge to the future. Good thing is, that you can put old battery back and drive, I had to keep car in garage and drive with diesel so it was little expensive to had my EV stalling for a while. Hope you have problem investigated soon!

Luv, Luv to You Dala, I have no doubt You will come up with something. perhaps we can all keep our eyes open for some and how many do you need?

Damn that's sad news. sorry it did not work. but I am insanely impressed with the fact that it said 200 km with the old pack. it is a real pity that diagnosing a batterypack isn't a thing until it is in the car. for reference I'm getting 60 km/charge in a 85% soh battery when charging to 80% so you still have a highly usable car.

That sucks, but I assume you going drop that battery for now and so maybe get it apart and see if any cells have expanded or corrosion etc and if by chance they have not, maybe remove weak cells and try to charge them up and see if that helps? Probably not but worth a shot until you can locate some replacement cells. Would have thought by now some third party could make cells for these. Must be a lot of Leaf's out there for it to be worthwhile now?

That sucks... 😩 Maybe moisture got in the pack, or faulty BMS? I think you should start with taking the battery apart as soon as possible. Might be an easy fix after all and no need for new cells.

Sad panda 😢. I wish you all the best Dala!!! The rust proofing looks great! I'm definitely following you on that one for my 2015! Any chance you have an ETA on restocking your new chipset canbridges.?! Much appreciated of all your help and support for these great cars!!!😊👍

The pack in your shed was painted in a wet environment, hence it's bubbling up under the paint.

Cheer up😊

Thanks for sharing also when things not go as planned! Do you have liberapay or something other than patreon to accept one time donations for making up for the loss? What about cells from 40kWh, not similar enough i guess?

We cannot always win, but your average is quite good

Hi Dala, I always watch and enjoy your content. You put in great efforts and are very good at what you do. Surely, it is a leak in the cells. When I am working with the hybrid batteries here in US, we just replace the leaking modules and also put a tape( I use making tape ) to avoid any contact between the metal surfaces. More, have you tried using new leaf modules from China as replacements ??????

Cheer up Dala, at least you still have the 40kwh to get back to, and a still running car! Some of us are on a 30kwh pack with 43% soh ;)

Hi Dala What about just bypassing the bad cells altogether ? (until you can get the replacements) Of course the BMS wire will have to be dealt with... I am just raising this possible workaround, in case your knoledge of the battery tells you it's worth trying.

New video series, Dala power up a 64 battery!😉😂😍😍😍

There is a connection to the chassis, cells that have lower voltage are being discharged over voltage measurement circuit. Remove the electronics if you wanna stop cells over discharging exceeding lower cut off limits. Check voltage between + and chassis, and - and chassis.

85 comments in and still nobody has said: Have you tried switching it off and back on again? Great rust proofing tips. I have had my 2011 leaf parked about 100m from the North sea for over a decade now and I suspect I'll soon be able to kick a hole in it. I'm frightened to look. I haven't had reason to be right underneath it for a few years!

Oh no! I am sorry about this :( Could it just be a cell imbalance which the balancers just need to balance out over time? How long has the battery-pack been disconnected/not charged?

It's not a total loss, the batteypack still have value. If you are patient, you will be able to find cells. Did I see some Exel poles, btw?

A pioneers life is not easy. Thank you for taking the slings & arrows so we don't have to! 🏹 On a positive note the 62kWh batteries should be more available in the future as these cars age out.

I love the way you say video 😅😅😅 Great wideo😂

Did you watch the recent Tesla Bjørn video on repair of a Leaf battery? It seems they got some cells for their battery but I don't remember if it was for this type or a different type of battery.

Sorry to hear......but good job anyway! Where do you get those battery packs from? I tried to find some in Switzerland. No chance AT ALL....

That's devastating 😢 Do you know anything about the vehicle that donated the battery? Forgive my ignorance, but it seems unlikely that a crash write-off donated battery that was physically intact would have suffered (or had already been experiencing) this issue, which suggests the battery fault was the reason the car was scrapped and they knew this when selling the battery.

Does your region salt the roads in winter? I'm wondering how rusty my 10 year old Leaf is likely to be. Maybe it doesn't matter, hyundai ioniq 38kwhs are coming on the used market for reasonable prices.

Can evhub in Norway help with battery cells ?

Sorry about your terrible luck! Do you have access to a megohmmeter? Hopefully you can find some replacement cells.

know the feeling.. My 30kWh is close to same state.. (is still run, but do not like to run fast)

I hope you will find an insulation issue outside of the cells themselves. Otherwise your best approach might be to sell off the good cells and you should get most or even all your money back in exchange for a lot of work - especially is the cells are rare.

Shame. Keep positive

Wow. That's a bummer. Is there anyway to test the battery cells before installation?

Dang man. Maybe a fitting or something:/ good luck

That's a shame.Try talking to Richard 'Moggie' Morgan at Electric Classic Cars, for suitable cells. He has several sources. Also try asking James of 'James and Kate', who has contacts, including his employer and Jonathan Porterfield, who might be able to help you to source the correct cells. I hope that you can fix this problem, Dala. Thanks for the video, and for the channel. Subscribed because of finding this one! So it's not all bad. 🙂👍
